Although screenshots and text descriptions could be faked, multiple players have uploaded videos of the bug in action, which is much harder. Below you’ll find examples from Scott M and Kinsey_92.

Also adding to the bug’s credibility is the fact that all of these pieces of content have been listed by DestinyTracker, a site that datamines Destiny, among other services.

You can also catch references to many of these events and locations if you explore Destiny thoroughly; the Jovian Complex, for example, is under the Hive Seeder just by the infamous loot cave in Skywatch on Earth.

The bug has caused some dissent among fans who believe it reveals expansion content contained on disc, although it should be noted that the bug only came to light this weekend, after several patches had already hit the game. Moreover, including a framework in your shipped game for expansion content to hook into once downloaded is a perfectly sensible strategy for a game like Destiny, which is intended to last for years via expansion and add-on content, and certainly doesn’t mean the content is already in place on the core disc.
